1. A Study in Jet Engine Control Control Structure Selection and Multivariable Design
Sammanfattning : Turbojet engines are becoming increasingly complex, with more control variables, to meet future demands on performance, fuel consumption and functionality. To utilise the potential of these engines, it is also necessary to use more advanced control concepts than conventionally used today. LÄS MER
2. Multivariate control design for a jet engine
Sammanfattning : .... LÄS MER
3. Development of Methods for Analysis and Optimization of Complex Jet Engine Systems
Sammanfattning : This thesis describes the development of GESTPAN (GEneral Stationary and Transient Propulsion ANalysis), a generalized system for the design, steady-state and transient simulation of gas turbine systems. Some of the main achievements in the thesis are related to the development of new algorithms or integration of existing numerics tailored to simplify the structure and use of generalized gas turbine simulation systems. LÄS MER
4. Estimation of Thrust and Health Parameters for Jet Engines
Sammanfattning : An advanced turbofan engine control system would benefit from an accurate thrust and engine performance estimate. Unfortunately, there is to date no reliable in-flight thrust measurement sensors available. LÄS MER
5. Dynamic threshold generators for robust fault detection
Sammanfattning : Detection of faults, such as clogged valves, broken bearings or biased sensors, has been brought more and more into focus during the last few decades. There are two main reasons why faults are important to detect at an early stage. LÄS MER
